Rookie second baseman Jedd Gyorko rejoined the Padres in Florida Friday as the club prepared to open a 10-game road trip against the Marlins in Miami (4:10 p.m.).

However, this was not the return that the Padres expected.

The Padres had hoped to activate Gyorko from the 15-day disabled list Friday.

But Gyorko will not be coming off the disabled list as planned. Instead of completing two rehab games with Double-A San Antonio before heading to Florida, Gyorko came out of the first game due to tightness in his injured right groin muscle and didn’t play in Thursday’s game.

Gyorko rejoined the Padres more to have his right groin strain re-evaluated rather than play. He might even need another rehab assignment before he returns to the active roster at a later date.

There was one roster change for the Padres Friday.

For the second time in three weeks, the Padres recalled right-handed pitcher Burch Smith from Triple-A Tucson to add length to the bullpen. Smith was 3-1 with a 2.57 earned run average in five starts with Tucson after going 0-1 with a 18.41 ERA in three starts (covering a total of 7 1/3 innings) for the Padres in May.

To make room on the 25-man roster for Smith, the Padres returned left-handed reliever Tommy Layne to Tucson.

The Padres Friday open their first of three three-city road trips this season with the first of four games against the National League’s worst team in Miami. With the Padres going to Boston and Washington after Miami, it is imperative that they play well against the Marlins.

Wednesday night’s 7-5, 13-inning loss to Philadelphia pushed the Padres under .500 for the first time in 12 games. The Padres swept a three-game series against the Marlins at Petco Park from May 6-8.

The Padres shut out Miami in two of those three wins – their only two shutouts of the season. Power-hitting right fielder Giancarlo Stanton was on the disabled list when Miami was in San Diego. He is hitting .254 with seven homers and 20 RBIs in 35 games. Outfielder Marcell Ozuna, 22, who was promoted to the major leagues when Stanton was injured, leads Miami with a .298 average and 27 RBIs in 51 games.The Marlins are 17-25 since being swept in San Diego.

This will be Volquez’s first appearance of the season against the Marlins and his first appearance at Marlins Park, which opened in 2012. Volquez is 3-4 on the road this season with a 4.73 ERA in eight starts. The Padres are 3-5 when Volquez starts on the road and also 3-5 in his eight starts at Petco Park this season. Volquez is 1-1 over his last five starts with a 6.84 ERA. The Padres are 2-3 in those five games.
